The UCL–Lancet Commission on Migration and Health steps into this political debate to provide evidence for cooperation and action on what is one of the most pressing issues of the 21st century. The Commission’s foundation is that migration and health are inextricably linked—and key to sustainable development. It provides a framework of migration as a dynamic process, providing evidence of the multiple factors that could be beneficial or detrimental to individuals and systems along the migration journey—at origin, transit, destination, and return. It documents the devastating impacts of forced migration, especially on girls and women, but also the overall benefits to the health of individuals and populations that migration generates. It lays out a research agenda to better ensure the health of migrants. Using the lens of health the Commission shows that migration policies can be both ethical and feasible—calling for governments, international agencies, and professionals to promote health in global mobility.
